AutoTest: Wrong file is opened when double click on a failed test

I have a CMake based project which copies all QML test files to the build directory. If I double click on a test in the test explorer or on a single test in the test result list, it correctly opens the file in the source directory. But when I double click on a failed test, it opens the QML file in the build directory. This is very annoying, because you start to edit the test file which will be overwritten on next build.
